Let's get the elephant in the room out of the way -- Tomorrow With You is a slow burner. It is not an action packed, quick paced drama. This was not an issue for me, nor did it make the drama boring at all. I think this quality of the drama pairs well with the fact that the drama circles around the concept of living in the moment, enjoying life for what is, and reveling in the little things. It does have a more serious and melancholic vibe, although there are many comical and lighthearted moments sprinkled into each episode.
The plot of the drama is very meaningful and emotional. It deals with the subject of fate and destiny, and how sometimes there are things that are inevitable. There will be moments of frustration and annoyance that despite knowing the future, things still go a certain way, but it doesn't bog down the drama. The drama embraces the fact that some people tend to make the same kind of choices or refuse to change, but the characters and the plot adapt and keep the story rolling. In the end, it is a great reminder to be present, enjoy life's ups and downs, and to always be grateful, and all those other feel good life lessons. The drama also tackles issues like love and marriage, corporate greed and crime, family relationships, friendship and frenemies, and life's regret. Overall, I felt that the story had the appropriate pace and unfolded in accordance with it's vision and purpose.
The characters developed beautifully and I felt that as an audience member, I really got to know them and accept them for all their strengths and weaknesses. The changes in the characters were gradual and reflective of what they were going through in the story. The actors did a great job in their respective roles, and were really effective in conveying deep emotions in dramatic scenes, as well as comedy in those lighthearted moments. I also love how it didn't shy away from kisses and love scenes (though still very demure). The couples in the drama had electrifying chemistry with each other, and even the whole group as friends really had a natural feel to it.
